Adaptation of Bread Wheat (Triticum Aestivum l.) Varieties in Lowland Semi-Arid Agro-Ecology of Ethiopia

Mihratu Amanuel Kitil, Tadiyos Bayisa Sarbesa

Adaption of existing varieties in seed system to variable agro-ecology is the good means in wheat production diversification process. To reduce risks with released varieties seed supply limitation as the irrigated agroecology is new emerging; popular varieties adaptability and yield potential identification is important. The adaptation trial of bread wheat varieties were carried out during 2018/19 and 2019/20 at rift valley from lower Awash to upper Awash on different locations. The analysis of variance (ANOVA) revealed highly significant difference (P≤ 0.01) among varieties and environments except NSPS (P≤ 0.05) and NKSP (ns). According to the mean separation table high yielding and adaptable varieties were identified (Ogolcho) over environments and recommended for irrigated lowland agro-ecologies.The AMMY analysis of ranking revealed that Ogolcho and lowland varieties performance were better and stable across different locations and more adaptable. The result of adaptation trials can make a lesson that aims adaptation of released varieties over variable environment to pick broadly adaptable varieties across diverse agro-ecologies.
